内容摘要:

Torelli problems for ramified Prym maps have been investigated in recent years by Marcucci-Pirola, Marcucci-Naranjo, Naranjo-Ortega and Ikeda. In particular, there is a Prym map which is both injective and relates moduli spaces of the same dimensions, namely the Prym map for double covers of genus 1 curves branched at six points. In this talk, we will give a characterization of the image of this Prym map. This is joint work in progress with S. Casalaina-Martin, M. Lahoz and J.C. Naranjo.
